Answer 1

Can you elaborate?  The questions that come to my mind are:  Is this an asp.net question?  Validate whose / what MAC addresses?  And what do you mean validate - compared to what?

I want to make sure that mac address is valid Ex: 12-21-223-1 it is invalid Mac address, so have any expression to validate mac address in c# ?

Use Regex.  https://docs.microsoft.com/en-us/dotnet/api/system.text.regularexpressions.regex.match?view=netframework-4.7.2 

A Regex pattern to match valid MAC addresses:

^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$

Why do you want to do this? You can't get the user's MAC address in ASP.NET.

The MAC address identifies systems on a network and not available outside the network or in a WCF request.
